The Intake Valve with OEM number 1003014FE010 is a direct-fit replacement engine valve for JAC N56 and Sunray vehicles equipped with the HFC4DE1-1C / 4DE1-1D (2.7L) diesel engine. This valve controls the intake of air into the combustion chamber during the engine's intake stroke.
Working Principle: The intake valve opens during the intake stroke to allow filtered air (or air-fuel mixture in indirect injection engines) to enter the cylinder. It closes during compression and combustion to maintain a sealed combustion chamber. Proper valve seating and stem clearance are critical for compression, power output, and emission compliance.

- Remove cylinder head per workshop manual. Disassemble valve train.
- Clean valve guides and seats. Check guide wear (replace if clearance exceeds OEM limit).
- Check valve seat width and concentricity. Re-cut or replace seats as needed.
- Install new intake valve. Check stem-to-guide clearance.
- Lap valve to seat if required. Verify sealing with marking compound.
- Install valve springs, retainers, and keepers per OEM procedure.
- Adjust valve clearance to OEM specification after head installation.
Valve clearance inspection every 40,000–60,000 km (verify against JAC maintenance schedule). Replace valves when clearance cannot be adjusted, or when compression loss, oil consumption, or valve noise indicates wear.
- Neutral carton or customized packaging available
- Suitable for: Wholesale distributors, engine repair workshops, JAC parts suppliers
- MOQ negotiable; samples available for quality verification
